Ototoxic Medications and Hearing Health | Salem Audiology

Every day, millions of Americans rely on medications to fight infections, manage heart conditions, relieve chronic pain, treat cancer, and address many other health concerns. These treatments can significantly improve quality of life and are often essential for maintaining good health.

What many people do not realize is that certain medications may also affect the sensitive structures inside the inner ear. This potential side effect is known as ototoxicity.

The term “ototoxic” means “toxic to the ear.” Although that may sound concerning, most people who take medications with ototoxic potential do not develop hearing loss. Understanding the possible warning signs and knowing your personal risk can help you protect your hearing and respond quickly if changes occur.

Whether you are beginning a short-term treatment or managing a chronic condition, learning about ototoxic medications and hearing health can support earlier detection and better communication with your healthcare team.

What Are Ototoxic Medications?

Ototoxic medications are drugs that may affect the inner ear or the nerves responsible for hearing and balance. The inner ear contains tiny sensory hair cells that convert sound vibrations into signals the brain recognizes as speech, music, and everyday sounds. Structures within the inner ear also help the body maintain balance.

Certain medications can influence these sensitive structures. The potential effect varies based on the medication, dosage, length of treatment, method of administration, and the patient’s overall health.

Possible hearing- and balance-related side effects may include:

• Hearing loss
• Tinnitus, or ringing in the ears
• Dizziness
• Unsteadiness
• Balance difficulties

Not everyone experiences these side effects. Many people complete treatment without noticing any change in their hearing. The goal is not to create unnecessary concern but to help patients recognize changes early and seek appropriate care.

How Can Ototoxic Medications Affect Hearing?

Unlike many other cells in the body, the sensory hair cells inside the cochlea have a very limited ability to repair themselves after they are damaged.

Depending on the medication, ototoxicity may affect blood flow to the inner ear, alter the chemistry of the auditory system, or directly damage delicate sensory cells. High-frequency hearing is often affected first, which means the earliest changes may not be obvious.

Instead of immediately thinking, “I cannot hear,” a person may notice that speech sounds less clear. They may have more trouble following conversations in restaurants, meetings, or other places with background noise. Certain consonant sounds may become harder to distinguish.

For others, the first warning sign may be ringing, buzzing, humming, or roaring that was not present before. Because these changes may develop gradually, regular hearing evaluations can play an important role in long-term hearing health.

Common Symptoms of Ototoxicity

Symptoms of ototoxicity vary from person to person. They may develop suddenly, appear gradually, affect one ear, or affect both ears.

Common warning signs include:

• Ringing, buzzing, humming, or roaring in the ears
• Hearing that sounds muffled or less clear
• Difficulty understanding conversations, especially in background noise
• Needing to increase the television or phone volume
• Dizziness or a spinning sensation
• Feeling unsteady while standing or walking
• New balance difficulties
• A feeling of pressure or fullness in one or both ears

If you notice any of these symptoms after beginning a medication, do not ignore them. These symptoms do not automatically mean the medication is responsible, but they should be discussed with your prescribing healthcare provider.

Important: Never stop taking a prescribed medication or change your dosage without first speaking with the healthcare professional managing your treatment.

Which Medications Can Affect Hearing?

Instead of focusing only on brand names, it is helpful to understand the medication categories most commonly associated with ototoxicity.

Aminoglycoside Antibiotics

Certain antibiotics, including aminoglycosides, may be used to treat serious bacterial infections. These medications can be highly effective and, in some cases, lifesaving. However, prolonged treatment, higher doses, kidney problems, and other risk factors may increase the possibility of hearing or balance changes.

Chemotherapy Medications

Several chemotherapy medications, particularly platinum-based agents such as cisplatin, have been associated with hearing loss and tinnitus. This is one reason some oncology teams recommend hearing evaluations before, during, and after treatment.

Hearing monitoring does not replace cancer treatment. It gives the medical team additional information that may help them evaluate changes and discuss available options.

Loop Diuretics

Loop diuretics are commonly prescribed to remove excess fluid and help manage conditions such as heart failure, high blood pressure, or kidney disease. In some circumstances, particularly when administered intravenously or at higher doses, these medications may affect hearing.

High-Dose Aspirin and Salicylates

Low-dose aspirin taken under medical supervision is generally not associated with the same level of hearing risk as high-dose use. Higher doses of aspirin or other salicylates may cause temporary tinnitus or changes in hearing for some people. These symptoms may improve after the medication is adjusted by a healthcare provider.

Other Medications

Some antimalarial medications, immunosuppressants, and anti-inflammatory drugs have also been associated with hearing- or balance-related side effects in certain patients.

The presence of a medication on an ototoxicity list does not mean everyone who takes it will develop hearing loss. Medication benefits, dosage, health history, treatment length, and individual risk all need to be considered by the appropriate healthcare professionals.

Who May Be at Greater Risk?

Several factors may increase a person’s likelihood of developing medication-related hearing changes.

Risk may be higher for people who:

• Already have hearing loss
• Are over age 60
• Have kidney disease or reduced kidney function
• Take more than one medication with ototoxic potential
• Receive higher medication doses
• Require long-term treatment
• Are undergoing chemotherapy
• Have a history of significant occupational or recreational noise exposure
• Have previously experienced a reaction to an ototoxic medication

Having one or more risk factors does not mean hearing loss will occur. It means that baseline testing and continued hearing monitoring may be especially valuable.

Why Baseline Hearing Testing Matters

One of the most useful tools in hearing healthcare is also one of the simplest: a baseline hearing evaluation.

A baseline hearing test measures your hearing before a noticeable change occurs. Think of it as creating a detailed snapshot of your hearing health at a specific point in time.

If hearing changes develop during or after treatment, your audiologist and medical provider can compare your new results with the baseline. This provides more reliable information than depending on memory alone.

Baseline hearing testing may be especially valuable for people who:

• Are preparing to begin chemotherapy
• May require prolonged antibiotic treatment
• Take medications known to have ototoxic potential
• Already have some degree of hearing loss
• Have multiple health conditions that increase their hearing risk
• Frequently work or spend time around loud noise

A baseline evaluation does more than identify existing hearing loss. It creates a reference point that can help guide future monitoring and hearing-care decisions.

Monitoring Your Hearing During Treatment

The appropriate hearing-monitoring schedule depends on the medication, dosage, treatment length, health history, and recommendations of your medical team.

Some patients may only need a baseline evaluation and a follow-up test. Others may benefit from more frequent monitoring throughout treatment.

These follow-up evaluations can identify subtle changes before they begin to interfere with conversations, work, relationships, or daily activities. If a change is detected, your audiologist can share the findings with the appropriate healthcare provider and discuss hearing-support strategies with you.

Audiologists do not prescribe or discontinue medications. Instead, they work as part of the larger healthcare team by measuring hearing, documenting changes, and helping patients understand their hearing and balance symptoms.

How to Protect Your Hearing While Taking Medication

Not every case of ototoxicity can be prevented. However, several practical steps may help you monitor your hearing and reduce other avoidable risks.

• Take medications exactly as prescribed.
• Do not stop a medication or change the dosage without medical guidance.
• Ask your provider whether hearing changes are a known potential side effect.
• Report new hearing, tinnitus, dizziness, or balance symptoms promptly.
• Use appropriate hearing protection around loud machinery, music, firearms, or recreational noise.
• Avoid unnecessary exposure to loud sounds during treatment.
• Stay hydrated when medically appropriate.
• Attend recommended follow-up appointments.
• Consider baseline and periodic hearing evaluations when recommended.
• Keep an updated list of medications and supplements for your healthcare providers.

These steps cannot guarantee that hearing changes will be prevented, but they can support earlier detection and more informed care.

What Should You Do if Your Hearing Changes?

If you experience new hearing loss, tinnitus, dizziness, or balance problems after starting a medication, contact the healthcare provider managing that treatment. Explain when the symptoms began, whether they affect one or both ears, and whether they are constant or come and go.

You may also benefit from a comprehensive hearing evaluation. Testing can help determine whether a measurable change has occurred and provide information that can be shared with your medical team.

Seek urgent medical attention for sudden hearing loss, severe dizziness, new neurological symptoms, or symptoms that make it unsafe to stand or walk. Sudden hearing loss should be evaluated promptly and should not be treated as a routine hearing concern.

Frequently Asked Questions About Ototoxicity

Does taking an ototoxic medication mean I will lose my hearing?

No. Many people take medications with ototoxic potential without experiencing hearing loss. Risk depends on the specific medication, dosage, treatment length, health history, and other individual factors.

Can medication-related hearing loss be temporary?

Some medication-related hearing changes may improve after treatment or after a healthcare provider adjusts the medication. Other changes may be permanent. The outcome depends on the medication and the way it affects the auditory system.

Can low-dose aspirin cause hearing loss?

Low-dose aspirin taken for cardiovascular health is generally not associated with the same risk as high-dose aspirin. Higher doses may cause temporary tinnitus or hearing changes in some people. Discuss any symptoms with the provider who recommended the medication.

Should I stop my medication if ringing begins?

Do not stop a prescribed medication on your own. Contact the prescribing healthcare provider and explain the symptoms. Your provider can determine the safest next step based on your medical needs.

When should I schedule a baseline hearing test?

Ideally, baseline testing should occur before beginning a treatment known to have ototoxic potential. If treatment has already started, testing may still provide valuable information. Ask your medical provider or audiologist about the most appropriate timing.

Final Thoughts

Most medications associated with ototoxicity are prescribed because their medical benefits outweigh the potential risks. The goal of discussing ototoxic medications and hearing health is not to create fear. It is to help patients recognize warning signs, communicate with their healthcare team, and take an active role in protecting their hearing.

If you are beginning a medication that may affect hearing, or you have noticed ringing, reduced clarity, dizziness, or balance difficulties, a comprehensive hearing evaluation may provide valuable information. Establishing a baseline early makes it easier to identify and document changes over time.
